SHU TTLE-POSI'IION IN G MEANS FOR FILLING-REPLENISHING LOOMS.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed September 13,1906. Serial No. 334656.

To all whom it may concern:

Be it known that JOHANNES GABLER, head foreman, 32 Altkircherstrasse, subject of the German Emperor, residing at Miilhausen, in the Province of Alsace and German Empire, have invented certain new and useful Improvements in Shuttle-Positioning Means for Filling-Replenishing Looms, of which the following is a full, clear, and exact description. I

This invention relates to apparatus for securing the shuttle of power looms in their shuttle-boxes in the position fit for the replacing of the empty pincops in the shuttle by a full one.

The accompanying drawings show one construction of apparatus in accordance with this invention; Figures 1, 2 and 3 being respectively a front view, a top plan, and a side elevation of the loom with its lay, while Fig. 4 is a diagrammatic representation of one method whereby apparatus in accordance with this invention is connected with the' weft fork. i

Referring to the accompanying drawings, the guide b which is firmly secured to the lay a has journalcd in it a vertical shaft 0, to the upper end of which is attached the bent arm d and to its lower end there are socured the striker e and the pulley f. The spiral spring 1', which is attached to the lay as by a bracket 71 and the action of which is neutralized when the striker 0 comes in contact with the lay a, is connected with the roller f by means of the chain 9. The bent arm (I, when at rest, is parallel to the lay a, as shown in Fig. 2.

As the lay moves forward in the direction of the arrow j thebent arm (2 comes in contact with the roller lon the lever in n mounted on the frame I of the loom which forms a stop, and is caused to assume the position indicated by dotted lines in Fig. 2, the shuttle being thus, when the impulse is too powerful, prevented from re coiling; while, when the impulse is too weak, the shuttle is by means of the arm d pushed into its proper position in the lay.

The lever m n is mounted to rotate around its pivot n and is held up by the action of a spiral spring 0 with which it is connected through a chain 9 which passes over a guide pulley p and around the pulley 1'. The lever in question is at the right moment moved downwards by means of a chain t suspended from the pulley s and lever mechanism actuated by the weft fork or the feeler. When the lever m n is in its higher position its roller is is raised out of the path of the bent arm (1, while when the lever is in its lower position its roller comes in contact with this arm. Consequently the safety apparatus is actuated only when it is necessary for the shuttle in the shuttle box to assume the position requisite for the replacing of the empty pincop by a full one.

Fig. 4, as already stated, represents diagrammatically the method of connecting the safety apparatus with the weft fork. The weft fork u is pivotally mounted upon the upper part 1) of the lever 11, w, a, the free end a; of which is connected with the lever m n through the chain t. If, when the shot miscarries, the weft fork it passes through the grid y pertaining thereto into the path of the lay, its heavier rear end, which is formed as a hook, will engage with the weft hammer z, 1, 2, the portion 2 of which rests upon the eccentric 3 which is driven from the mainshaft 6 by means of the wheels 4, 5. The weft hammer 2 will upon its backward movement in the direction of the arrow 7, carry the lever 'u, w, 2:, of the weft fork along in the same direction, the roller is of the lever m n being thus lowered and so brought into contact with the bent arm d, which is thereby moved into the position (1.

What I claim and desire to secure by Letters Patent is:

1. In a shuttlepositioning means, a lay, a shaft journnled vertically at one side thereof, the upper end of the shaft being provided with an arm, and the lower end with a striker and a pulley, a coiled spring connected at one end with the lay to the rear of the shaft, a flexible connector from the other end of the spring to said pulley for normally holding the striker against the side of the lay, a stop for engaging with said arm and moving its free end in front of the shuttle box, means for moving the step into its operative position and means for moving the step out of its operative position.

2. In a shuttle-positioning means, a lay, an arm pivotally mounted thereon, a lever provided with a roller forengaging with the arm and moving its free end in front of the shuttle box, a spring for normally holding said lever and stop in an operative position, a second lever connected at one end with the slop lever and provided at the other end with a weft fork, and means adapted to be engaged by the weft fork for causing the stop lever and its roller to be moved into the operative position.

3. In a shuttle-positioning means, a lay, an arm pivoie ally mounted thereon, a stop for engaging with the arm and forcing its free end in front of the shuttle box, means for moving said stop into its operative position, a lever for actuating said means, a shouldered weft fork pivotally connected with one end of said lever, a weft hammer, one end of which is adapted to be engaged by the weft fork, a cam for engaging with the other end of the weft hammer, whereby the stop is caused to engage with said arm and actuate it whenever the weft fork is in engagement with the weft hammer and means for moving the stop out of its operative position.

In witness whereof, I subscribe my signature, in presence of two witnesses.
